Winged Scapula and Damaged Long Thorasic Nerve

I am 24 years old. I am a bridge inspector for the state of louisiana. I do alot of overhead climbing and lifting. I have been dealing with winged scapula for almost 4 years now. It started out with a little pain then gradually got worse. I saw a specialist back in November. He informed me that the damage to the nerve was a result of a virus. He put me in a brace and in physical therapy. It helped but only for a short period. It since gotten bad again. I experience severe pain in my shoulder blade and all the way down my left arm. At times I cannot even move my arm bc of the pain and stiffness. I have experienced partial numbess and tingling in my left arm. The specialist I went to said that if the therapy doesn't work he would like to do surgery. The surgery he wants to do involves cutting a muscle out of my chest and securing it to my shoulder blade. This requires a 6 month recovery time. I cannot afford to take off that much work. I want to know is there any other surgeries to fix this problem and what are the chances to regain movement and ease the pain.
